FLUID-GONTRLLENG Application led December 29, 193.3.

Be it known that HENRY SrnenN, e citizen or the United States, residing at Kansas Cijiz in the county of Jackson and Stute of M oui-i. have invented certain neu sind userui niproemeuts in Fluid- Coniroiiing Apparatus, of 1which the foiA roving is sgeciiicatien,

invention relates to liuid continuing apparatus, und my objecty is to produce new sind useful mgiperaius this character wher-cbj," or other Huid may be cuiJ ofi3 from :i fuiiding either manually or einem n'uiicelijx.

The epg'mrutus iuciudes u waive to cont-roi die 'fion' fluid through the service-pipe ieediug' into the building and means to coniroi seid ifaife, and in order that the invention may be uiiy.- understood, reference Wiii non; ne made io the accompanying dran-ine" in which:

'in carrying out the invention i employ a mire l.; which is preferably self-dosing. aid valve communicates with the servicepipe 2 vceding from the street main into the building (not shown), and is preferaeiy, placed in n pit 3, ioceted outside the foundaion or" die building and provided Wiii a iid through jrile removal of which access may had o the interior of scid pit. The 'faire uriier inclosed in a casing' 5, so inzit it cannot be tampered with oy unauthorized persons who might remove the iid from the pit.

The vmire, is pro 'ided with a Weighiedlever 6, whereby it is closed, and the free end of seid lever is provided with. a slotted stop T adepte-d to Contact with an arm 8 to Ypreventsraining he valve after the same closed. Arm E5 is secured to the underside of the mire by a screw 9, the upper ypointed terminal of which projects into he faire und forces the valveplug 10 firrniy ejziinst its seat 1l when the valve closes. Juive- Speccaton of Leners "fateci,

iGG

maire the conduit 38 moreor .less tortuous,

as shown in Fig. 1, and in orderthat the rodv may follow such'conduit, its intermediate portion is made flexible,y as' indicated at 40. The upper end of the rod is bent at right angles thereto to form a handle 41, adapted to rest upon the upper end of a safetymember 42 to hold the rod in raised position. Safety-member 42 Ais secured to the bottom of the box, which is provided with a lid 43 l having a notch 44 to fit over a staple .'45,

l stated, is as follows:

adapted to receive `a lock to secure the door in closed position. lln some instances the door may have. a glass front, so that it may be broken in caseof emergency,` if desired, to' ain access to thehandle 41.

nf ractice, box 39 is preferably located outsi e of the building, or other accessible int, so that it can be easily' found when 1t is desired to close the valve and cut olf gas to a burning. building.

The operation of the apparatus "brielly To cut off the flow of gas or other fluid into a building on ac count of fire, or for any other reason, door 43 of the box is either unlocked or 'broken open and handle 41 is'l grasped, raised u out of engagement with the lupper end or the safety-member 42 and turned forward to clear said.safety-member.y The rod 33 is then pushed downward tov actuate lever 29 and cause the same to 'withdraw the in 24 from the fusible link 23 and the gui `es 25.

The instant the fusible link 23 is released i from the pin 24, the weighted-.lever 6 automaticallyv closes the valve and thus cuts oi the flow of fluid into the building through the service-pipe 2. Should the valve, for any reason, fail to close when the fusible link 23 is released from pin 24, continued downward movement of the rod tips the o posite end of lever 29upward enoughy to clbse the valve through the intermediacy of pin 24, cable 28, and the cranloarm 27. Should the last-mentioned operation' fail to closethen valve by reason of the Alever 29,

' cable 28, or crank-arm 27, getting out of order, the valve will 'be positively closed by continuedv downward movement of rod 33,

which upnpassing the bifurcated end'31 of lever 29 comes into contactl with the slotted stop 7, so that suflicient pressure can4 .be exerted thereon to close the valve without fail. After the valve has been closed, it can not be strained or otherwise injured by further downward pressure of the rod'33, as further downward movement of said rod is checked by vits handle41 striking `the bottom of box 39, and spool 34 striking the slotted stop 7, which stop is held from furf ther downward ymover'nent by the arm 8,?

uponwhich its rests. To open or reset the valve, handle 41 is grasped and drawn upward and turned inward into engagement with' the upper and oi the selbigeamenacee scribed: y into a `b' 42, carryingfthe rod 33 upward therewith and supporting the same in its raised position, as shown in Fig. 1 of the drawing. As the push-rod 33 moves upward, flange 35 of spool 34 passes above the bifurcated end 31 of lever 29 by moving said bifurcated end upward on the pivot 32, and immediately after flange 35 passes above said bifurcated end 31, the same is automatically restored to normal position (see Fig. l), by itsl counterweight 3l and spring 31. .'Weigl1t--' ed-lever 6 is then swung upward to open y the valve, and heldv in4 raised position by the pin 2,4, the reduced lower end of which is inserted through the iusible link 23 and the guides 25. ShouldV a lire originate'close' to the' valve and fuse the linlr 23, the valve is automatically closed by its weighted lever 6.

Cable 28 and crank-arm 27- are used cliiey as precautionary measures to insure closing of the valve manually, and may be dis- "pensed with, as may also the fusible linlfL 23.

when-.fthe pit contsining'the valve is located the character def,

pipe, means to assist in normally holding said valve open, fusible means enacting with the first-mentioned means to normally hold the valve open, and a 4push-rod to actuate said Erst-mentioned means to allori7l the valve to close.

2. In an apparatus of the character described, a service pipe'to conduct fluid into a building, a sell-closing valvetu control means to normally hold said valve" open, a rod to actuate said means to allow the valve to close, said rod having a handle, a box inclosing said handle, anda safety-member which holds the handle in position to'prevent closing of the 'box until said handle is restored to normal position.
